C # Remove the leftmost column of the winform datagridview Control

It is not the first column of the index data, but the column on the left of the index data that selects the row. The column with the Black Triangle appears.

Using datagridview to replace ListBox and ComboBox is very effective. It not only has a simple connection with the database, but also allows you to customize display styles and provides powerful support for data operations.

What I 've always been upset about is the clever navigation column on the left, just like excel.

 

The removal method is simple.The rowheadvisible attribute is set to Fals.E.

 

Although it is a very simple setup, I think it is simple to know, but it is a headache to death (I have been worried about this problem for a few months), so I want to record it and hope it will be useful to everyone.
